U151 Teardown

Shout out to Gary for still replying on a 7 year old video. Looking to import a MarkX 4wd from Japan and came here to ensure this wasn't a CVT type tranny. Awesome video. Thanks!

[@michaelwalsh864]

Thank you for this great video. I'm having a problem with my 2004 Highlander 3.3 V6, AWD with the U151F transmission. My wife was driving down the highway (she is a good driver) and I was asleep in the passenger seat. Suddenly there was a "Boom" which felt like she had driven through a pothole and the suspension bottomed out. But there was no pothole. She carefully drove off at the next exit and there was another Bang as something hit something else. It felt like another pothole, but that section of highway does not have any potholes. She carefully drove home (12 miles) on back streets. The Highlander had trouble pulling away (making whirring noises) from red lights and a lot of trouble reversing into our driveway about 1 in 20 up grade, she had to rev it high before it would move. When I inspected it the next day I found the rear right drive axle was gone; as in "Gone, it was not there". It had snapped off inside the outer CV boot. Only about three inches of axle shaft was still attached to the outer CV joint. All the rest was missing and simply not there any more. The missing part of the axle was probably out on the highway somewhere. I replaced the axle with a new one but the transmission still does not respond well. I assume something is broken inside and I'll have to replace it. QUESTION 1: Does anyone know if I can remove just the transmission by itself from the Highlander, or do I need to remove the entire engine and transmission as a single unit and then separate them after I have them out? Question 2: I'm assuming that I need to replace the transmission. But I'd hate to do that and then find the problem was just with the control circuit, or something like that. Does anybody have any good diagnostic tests that I can try to prove one way or the other whether I need to pull out the transmission or not? I have rebuilt a couple of GM transmissions and an old Toyota Corolla transmission but these cross-mounted engines are a real pain for trying to replace a transmission. Thanks Mike

[@GaryFerraro]

so with the new axle in place, the car does not move? I would check the rear diff and Transfer case too. are all 4 tires exactly the same?

[@michaelwalsh864]

​@@GaryFerraro Thank you Gary. All tires are the same except for minor differences in tread wear but not amounting to more than about three mm of tread depth difference between the best and worst tires. I have checked the rear diff. It turns nicely and easily with no noticeable noises. Have not checked the transfer case yet. The engine starts and runs normally. When I select Reverse or Drive I do not notice any harsh transmission noises. The car is parked on a concrete driveway with a slight down slope forwards of about 1 in 20 - 1 in 30. I normally reverse it in up this gentle slope to park it. It used to be that if I reversed the car into the driveway, placed it into Park, turned the engine OFF, then took my foot off the brake it would roll forward slowly a few inches until the Park pawl engaged and stopped it. Now, in Neutral and the engine off it does not roll forwards down the slope. If I put it into Drive with the engine at cold idle (around 50F) it starts to move forward then stops. I need to rev it up to somewhere around 2,000-2,500 RPM before it will move forward. If, from stationary and with the engine at cold idle, I put it into Drive and allow it to move forwards a foot or so, then put it into Reverse it will move in Reverse under idle for about a foot then stop moving. I need to rev it to around 2,000 RPM or so to get it to move any further in Reverse. Under high revs it does move but very sluggishly as it would if was in soft sand. I have the rear end up on jack stands at the moment, and the front tires chocked. I have the transmission in Neutral. The Highlander has a bypass button that one can press to enable the gear selector to be moved out of Park without the key ON, and/or the engine running. Tomorrow I will disconnect the rear drive shaft at the second universal joint behind the transfer case and see if I can get the drive shaft to turn by hand with the transmission in Neutral and the engine off. Tomorrow I will also remove the transmission pan, and drain the ATF and the filter, and see what they look like. I'll also smell the ATF for any traces of a burned smell. I will let you know what I find. Thank you Mike PS. When I rebuilt the two GM THM 350 transmissions and the Corolla transmission about 35-40 years ago they all performed beautifully when I re-installed them back in their respective cars. (I am a semi-retired mining engineer and a self-taught mechanic. I have a fairly good understanding of hydraulics and fluid mechanics)

[@GaryFerraro]

@@michaelwalsh864 ok, let me know, just point of info, with the rear drive shaft removed the car may not move or hold in park, let me know what you find

[@michaelwalsh864]

@@GaryFerraro Hi Gary. This is what I found. And firstly. I had transmission in Neutral because I didn't want the Park pawl interfering with any movement. Engine and ignition were off. Front wheels were on the ground and chocked. Rear end - observations and symptoms. I raised the left rear tire so that it was clear of the ground. I had the car supported on a jack stand. I left the right rear tire on the ground to provide frictional resistance to rotation. I set about disconnecting the rear drive shaft at the second universal joint (UJ) behind the transfer case. It was a struggle. The four UJ bolts had been done up with green loctite and were very difficult to remove. One of the top UJ bolts was nearly impossible to get moving, or get a wrench on, and the drive shaft would not rotate to get it into a more favorable position. I grabbed the left rear tire and tried to rotate it by hand but it would not move. I then jerked it forwards as hard as I could by hand so that the momentum of the tire would jerk on the drive shaft and rotate it a little each time. After about 6-8 jerks the drive shaft had rotated about 180 degrees so I could get to the UJ last bolt and undo it. I disconnected the drive shaft. The rear part of the shaft which goes through the rear diff to the rear tires rotated easily and smoothly, and made the left rear tire, which was off the ground, rotate easily. The front portion of the drive shaft that went into the transfer case would not move. I had put about 80 N.m (Newton,metres) of torque (about 60 ft.lbs) on it while I was trying to undo the UJ bolts but the shaft going into the transfer case did not rotate. I then re-connected the UJ and lowered both rear tires to the ground and chocked them. Front end. Transmission still in Neutral. Engine off. I raised the front end a little and supported most of the weight on jack stands. The right front tire had enough ground contact to provide frictional resistance to rotation. I raised the left front tire just clear of the ground. It rotated very easily by hand. Quite different from the rear. Transmission. I drained the ATF and took off the transmission pan. The ATF was quite thick (high viscosity) like an SAE 40W or 50W oil. It was dark and discolored but it did NOT have a burned smell when I rubbed it between my fingers. The pan magnet had some very fine metal fragments on it but none were big enough to feel. I estimate most fragments were smaller than about 50 microns. There appeared to be less than about 1 cc in volume of particles on the magnet. The pan itself was quite clean. There were no pieces of metal or rubber (o-rings, seals etc) in the bottom of the pan. That was it for today. The sun was going down and I'd bashed my head on something sharp under the car and drawn a little blood. I use gloves to protect my hands from cuts and bruises but heads under cars are a little harder to protect. (Still smiling though) Mike

Hi Garry. Question about lockup selenoid and lockup. I hope you can help me. During drive when I remove a foot from gas pedal I hear a whirling noise. I checked that usually it happened when my speed is about 35mph (more or less), pedal gas is released, transmission is in 4 gear, lock-up selenoid is ON but ECU reports that lock-up indicator is OFF. When I gently press on gas pedal, lock-up selenoid became OFF and noise disappear. I've heard that U151 attach lockup during decceleration on 4 gear. Could it be a torque converter or lock-up selenoid ? ECU doesn't report any error yet. Thanks for your help.

usually when you release the gas the converter comes off, if the converter does not release on downshifts when coming to a stop the engine will stall. Are you sure your not hearing a diff noise?

Reverse rearward is okay even when cold engine or hot engine.

Hello, not sure if you can give me some insight or not but hear goes. I have an 04 Toyota Highlander awd. There is a bearing noise while driving. It is definitely in the trans. This noise will come and go as you load the left front side of the vehicle. It will also stop if you hold the LF wheel still (on a lift while in drive) I'm currently suspecting the carrier bearing for the differential in the trans. Also plan on replacing the support bearing for the center differential. U151f trans.

[@GaryFerraro]

Al H Are you sure it's not a wheel bearing. If it were a diff bearing inside the trans the noise would not change. Sounds like a wheel bearing. Check both left and right side

[@alh1323]

Gary Ferraro I have checked both front bearings. A stethoscope puts the noise in either the trans or front transfer case. I should add I am a 10 year toyota master tech. I have never had one like this.

[@alh1323]

Gary Ferraro no it's a support bearing for the under drive. It stays in the bell housing cover. This bearing has been discontinued by toyota. I am in southern pa. Another question. Should the half shaft that runs the transfer case (the part in the differential, in the trans) be notchy when turned or smooth?

[@tombiondi9969]

Hi Gary, I have a question for you. I’m doing an engine swap on an ‘09 Highlander AWD. I mistakenly removed the nuts and started to pry apart the transfer case thinking it was part of the transmission/bell housing connection. You can see the one you removed in the background of your video. Should I completely separate it and reapply the pink RTV (also in your video) which goes around the rubber o-ring or do you think I can get away with just bolting it back together? In researching this, I also came across a TSB from Toyota about these transfer cases and inner seal/vent leak. In reading that, I saw reference to the RTV and seal I mentioned above. I only stumbled across this in researching my situation and deciding whether I should dig deeper..... thanks.

[@GaryFerraro]

You can probably get away with just bolting it back together, how does the RTV look?, is it still intact?

[@tombiondi9969]

Gary, thanks for the reply. I can’t really see it clearly, the flange is separated about 1/4” and then I stopped. If I understand correctly, the RTV doesn’t really seal anything unless that o-ring fails. Is that your understanding as well?

[@GaryFerraro]

@@tombiondi9969 correct

[@thee_chrisrivero]

I have some questions that hopefully you can answer. I am currently dealing with a 2006 Sienna with the U151F AWD and experiencing a grinding noise when in drive or reverse that I suspect coming from the transfer case. I have pulled the housing off of the rear of the transfer case and the output shaft seems to be loose/wobbly which I feel confirms a little more of this being a transfer case issue. My questions are, if I pull the CV shafts from both sides, will the transmission still engage the transfer case when I turn it on and put it in gear to see if the grinding continues or would I need to completely remove the transfer case? And would you say this is an OK way to troubleshoot the problem through process of elimination or could I possibly cause damage to the transmission? (assuming there is none at the moment)

[@GaryFerraro]

Just to confirm, you only hear the noise while moving? All tires exactly the same size and model?

[@thee_chrisrivero]

@@GaryFerraro Thanks for the quick response! Yes only when moving and the tires are the same. Here is a little more of the story. The vehicle stopped being able to move like something had locked up. The driveshaft to the rear tires was removed and that allowed for the vehicle to roll. The driveshaft was reinstalled and then the car was able to move in drive or reverse but now with the grinding noise. Lifted all four tires and removed the driveshaft again to eliminate the rear differential but still getting the grinding noise. Grinding happens in drive or reverse but not in neutral. Grinding also stops when brakes are applied and the tires stop. I pulled drain plug to the transfer case and a very tiny amount of gear oil came out. Like just enough to fill the palm of your hand. The drain plug also had a fat chunk of oily metal shavings caked on it. I pulled the rear housing to the transfer case and was able to shake the output shaft a bit. It's not a super crazy amount but it is enough to where I know that something is not right in there. So now I am continuing with process of elimination and want to know if it is going to tell me anything by removing the cv axles and putting it into drive or if I just need to remove the whole transfer case and run the transmission really quick to listen for grinding. I just dont know if I can potentially mess up the transmission by running it with the transfer case removed. I'm just assuming that the transmission is ok at this point. I understand that I will probably lose some tranny fluid when I run the transmission with the transfer case removed but it will only be for a few seconds to listen for grinding since the grinding happens as soon as the tires are moving. Hope this info helps you to understand where I am at with it right now. Thanks again for your time!

Got a 2005 rx330 that needs a trans rebuild soon. It is slipping all gears especially the first gears and also when downshifting. 140,000 miles.. I drained the trans fluid 7 times, maybe I should NOT have. How long can it go slipping and hard shifting, can anything help? I refilled with maxlife synthetic first couple dumps, then to aisin t4 for 3-4 drains, then actually back to maxlife last couple drains (it seemed to shift marginally better w maxlife) aamco says the TC is shuddering/going out and spreading metal throughout the system, eating itself up.. they won't change the filter, says it won't help..? i am seeing tiny metal particulate in every drain. any recommendations? It's 5k for a rebuild! Not to mention the timing belt..

It's u151e. Also what is more reliable when checking the dipstick, cold or hot?? I have checked the dipstick probably a thousand times and the hot parameter always has weird inconsistent readings (ie low then overfull then midway then overfull then overfull then low) but cold is always consistent, however in actuality I dont know what the more accurate level is to judge by, the cold or hot level?? It reads just under the low level when cold (bad territory?) However it also reads midway and full when hot...? I don't want to overfill either, so...?

Thanks so much for the update. I was thinking about doing that, your update confirm I'm on the right direction. Thanks for sharing your experiences and knowledge!

Hi I have a U250E transmission with a sluggish movement on reverse. Each time I tried to pedal harder on reverse it acts like there is no power to propel the vehicle and at this point check engine light pops up with a p0500 code( vehicle speed sensor) any pointer to the right direction would be greatly appreciated

[@GaryFerraro]

Does it seem like it's binding up?

[@mayowaodus6310]

@@GaryFerraro I really do not know what you mean by binding up but do you mean like it freezes.what I really do mean is it engages in reverse but when you try to move on reverse it’s sluggish and even doesn’t want to go uphill. No force to propel the vehicle

[@GaryFerraro]

@@mayowaodus6310 Does the engine race up and the car not move that great in reverse?

[@mayowaodus6310]

@@GaryFerraro yes that’s what I meant. Doesn’t move that great on reverse

[@GaryFerraro]

@@mayowaodus6310 So it slipping in reverse, that is a mechanical problem, may have a damaged clutch pack

[@Cistemautoshop]

Sir what are the functions of those sensors

[@GaryFerraro]

Fed back to the computer so it knows when to fire the solenoids and when to shift the car

[@issaalazzabi6087]

hi gary i have 2009 toyota camry u250e the trans is not shifting after inner cv axel replaced

[@GaryFerraro]

Not shifting as in failsafe? any codes? or is it stuck in first gear? anything else done other than axle?

[@autocrownz8078]

Gary Ferraro I guess the CV was replaced when the trans was still not at room temperature... That problem is perculiar to the trans

[@ThugByChoice]

What was the milage?

[@spencercpu1983]

that ATF looks real dark and dirty.im sure dirty atf isn't good for the solenoids.

[@petarbaev8064]

Auto transmission U151 probably 4x4 and U151E FWD it is all same transmission without converter 4x4 yes or no ? For me look same but outside only 4x4 part is added to other yes or no?

[@GaryFerraro]

No different, the final drives are different,has extra shaft, right side axle, axle seal is different, internals should be the same

[@issaalazzabi6087]

Gary do you replace the solenoid on u660e as well and Very big thanks to you gary

[@GaryFerraro]

Are you working with a 4 cylinder or a 6 cylinder?

[@issaalazzabi6087]

Gary Ferraro 6 cylinder its a 2007 lexus es350

[@GaryFerraro]

The 6 cylinder transmissions, the cases go bad where the center bearing rides, the ones i had, the damage was bad, it would cost to much to rebuild so i got a low mileage unit, i actually never rebuilt one yet.

[@johnbarry8185]

Gary, I have my transmission apart, trying to find out which solenoids to replace. The van threw a code P0776, and the ones that are located on the valve body ohm out to just under 13 ohms, and the others ohm out to 5.5 ohms. Do you open the valve body, at all? Some of the spring loaded shafts are sticky. Any help would be appreciated.

[@GaryFerraro]

What is the definition of code P0776

[@GaryFerraro]

What is the year, make and model of the car?

[@johnbarry8185]

It is a 2004 Toyota Sienna.

[@johnbarry8185]

..."Solenoid B" problem. I can get the exact definition later today.

[@GaryFerraro]

The code is Solenoid B performance, this is a mechanical code, how is the car shifting up through the gears, any slipping or flaring?

[@issaalazzabi6087]

Hi gary what is the diference between u250e or u241e is the direct drum and the clutch is the same

[@GaryFerraro]

The 250 is a 5 speed tans, the U241 is a 4 speed trans, parts are not the same

[@issaalazzabi6087]

Gary Ferraro how about u150e and u140e

[@GaryFerraro]

same deal, U150 is a 5 speed and the U140 is a 4 speed(the u140 transmissions geartrains always go bad) 2 different units

[@issaalazzabi6087]

Gary Ferraro why the direct clutch c0 always go bad in these unit

[@GaryFerraro]

These units have solenoid issues, i always change the SL1, 2 and 3 solenoid as well as the SLT solenoid, the solenoid may be mechanically bad causing the clutch not to fully disengage the clutch will drag and burn out

[@lolppfhd6178]

u151 sienna 2.3 shift clutch get burned I changed it 2 or 3 times and when I drive it again get burned so sir please reply me how I can fix it please I request you sir please help please reply

[@GaryFerraro]

first, do you have a scan tool to reset shift adapts. If that did not work, the problem most likely are the solenoids, you would have to change the SL1, SL2, SL3 and SLT solenoids and you would still have to reset shift adapts

[@maadenengineering9101]

،،Great ..thanks.

[@GaryFerraro]

Thank you

[@jeffstepp1969]

transtar has that direct piston 85bucks

[@GaryFerraro]

Thanks for the tip. i going to ask my rep tomorrow about, may have another to do.

[@WhatDreamsMayCome444]

With the 4 solenoids you change, do you happen to have the part numbers?

[@GaryFerraro]

I do not sorry, i purchase the OE solenoids through my supplier. The solenoids arer SL1, SL2, SL3 and SLT(pressure control)

Hi sir

Hello, what transmission problem are you having?

[@abuaglablola7821]

why you don't rebuild just teardown .

Hey Gary, I disassembled my 2006 rx300 and the back housing that connects to the direct clutch pack was worn out at the surface before the seals. The direct clutch pack was burnt. The car couldn't hold gear and was always downshifting. Any idea what could cause that or is it just a natural degradation issue on those transmissions? Also, after I replaced the clutch pack, the car drives better but it hesitates from stationary. Anything else I need to look out for? Thank you

[@GaryFerraro]

Back cover probably just worn out, i had to change a few

[@ThugByChoice]

What was the milage?

[@GaryFerraro]

Not Sure, sorry
